Re: [AMBER] TESTING RELATIVE ERROR over r ranging from 0.0 to cutoff

Hi Jeon,

The error is the NaNQ values for VDWAALS and EEL. This suggests you have
problems with your starting structure. Likely you have two atoms sitting
on top of each other. You can use the checkoverlap command in ptraj /
cpptraj or alternatively you can open it in a visualization program such
as VMD and take a look at the structure. You'll need to fix any steric
clashes before you can run a simulation.

All the best
Ross
